Well maybe dinosaurs have more in common with present-day birds than reptiles. Look at the pubic bone - - it's turned backwards, just like a bird. The vertebrae - full of hollows and air sacs, just like a bird. Even the word raptor means "bird of prey".
devon is a bird.
EDIT: As far as I know, there is no such thing as a "public" bone. Stupid internet. Stupid copy-paste.
I do believe that humans evolved from some kind of shrew like mammal that was capable of burrowing deep enough to keep itself cool after the meteor hit (throwing tonnes of burning material into the air which then descended and burned everything left... If there was still anything after that then all the dust in the atmosphere blocking out the sunlight and killing off the ecosystem should finish it off XD).
@giblit Yes, I know. I changed it to say pubic. The quote I copy-pasted from elsewhere spelled it public.
I would like to experience the learning process in an environment where people learned languages by sailing the globe and visiting vastly different cultures. I wonder what it was like back when the world was huge.
@Devonrevenge - You seem to make a fundamental assumption here which is not correct. Categories such mammal or amphibian are not clear cut and if you go far back along the timeline of evolution you can't say stuff like oh yeah and then fish evolved into reptiles. Evolution is messy.
Try to not see it as what type evolved into what other type. Although this might make pretty pictures in your head and on posters, it's not how evolution is. If you drew an accurate picture of evolution it would be messy with arrows linking species which evolved from others going everywhere and many creatures in-between, some of which are rather difficult to categorize.
I highly recommend you read 'On The Origin of Species' if you're really interested in this stuff. It will give you an incredible insight into the natural world.
